Mechanical Property and Microstructural Evaluation of Maraging Steels

Abstract

This report contains the results of a material characterization study which was conducted on various grades of 18 percent nickel maraging steel which have been considered for use as the sheath material for the kinetic energy M-735 penetrator. Investigated grades include the 200, 250, 300, and 350. Data presented and discussed are hardness, tensile properties, hoop strength, Charpy impact, and fracture toughness (KQ, W/A, and KId). Additional areas addressed include material processing, chemistry, cleanliness, and heat treatment. Results of the study indicate that the materials generally meet the requirements put forth in MIL-S-46850A, the military specification under which they were procured. The 350 grade is not included in this specification.
